This can be done at any time: Get any character, purchase or get equips/weapons that add HP (Health) and make sure you have a good amound of money (A smart thing to do would be to use a Prinny; they only cost 1 HL per revival). Equip, then un-equip the chosen items, and re-equip them again. After doing so, the selected character will end up with it's original HP and have the MAX HP from the equipment boost. If you can see, there is missing HP. Go to the hospital, pay the person to heal your character, and it will add HP Points into the total. Redo these steps and get your points in the hospital higher and higher. Eventually, the hospital rewards you with an item for the amount of points recieved. (This cheat is able to work with HP, SP and Deaths. HP = HP Equips, SP = SP Equips, Deaths = All-around statted item). When you get your reward, add it or swap it with another HP equip that is lower statted. Eventually, you'll be able to recieve equips that add much needed Health, SP or stats.
